Calculate the electricity bill amount for a month of 31 days, if d following devices r used as specified . 3 bulbs of 49 watt fr 6 hrs 4 tubes of 50 watt

fr 8 hrs A refrigerator of 300 watt fr 24 hrs Given the rate of electricity is RS 2 per unit ???

No. of bulbs = 3 Power = 49 watt = 0.049 kw Time = 6 hrs. Therefore, Energy = 0.049 X 3 X 6 = 0.882 kwh

No. of tubes = 4 Power = 50 watt = 0.05 kw Time = 8 hrs. Therefore, Energy = 0.05 X 4 X 8 = 1.6 kwh

No. of refrigerator = 1 Power = 300 watt = 0.3 kw Time = 24 hrs. Therefore, Energy = 0.3 X 1 X 24 = 7.2 kwh

Total energy consumed per day = 0.882 + 1.6 + 7.2 = 9.682 kwh Money per day = 9.682 X 2 = rs.19.364 Therefore, money required for a month = 31 X 19.364 = rs.600.28
